Introduction: Technology Sector Capital Flow Shows New Pattern
At the close of US stock markets on September 18, the technology sector capital flow showed a distinct rotation pattern. The AI hardware sector continued to face pressure, with capital continuously withdrawing. Meanwhile, defensive sectors such as utilities and healthcare attracted capital. The new energy vehicle sector in China, however, attracted capital inflow against the trend, thanks to superior delivery data. This capital rotation pattern not only reflects changes in market risk preferences but also signals that adjustments in the internal structure of the technology industry are accelerating.
AI Hardware Sector Cool Down: Dual Test of Valuation Repair and Earnings Expectations
The AI hardware sector continued to face pressure overnight. Major chip manufacturers such as NVIDIA (NVDA), AMD (AMD), and Intel (INTC) experienced widespread stock price declines. Data shows that net capital outflow from the AI hardware sector reached $1.8 billion, a new high in almost two months. Behind this phenomenon are several factors:
- Valuation Pressure: After a continuous rise, the valuation of the AI hardware sector is at a historical high, with some stocks having Price-to-Earnings ratios exceeding 50 times, far above the industry average.
- Earnings Expectation Adjustment: Several securities firms lowered their revenue expectations for AI hardware manufacturers for the second half of 2026, believing that the growth rate of AI infrastructure investment may slow down.
- Increased Competition: As more companies enter the AI chip market, industry competition is intensifying, leading to price pressure.
- Supply Chain Bottlenecks: High-end chip manufacturing capacity remains tight, limiting the expansion pace of some AI hardware manufacturers.
Industry analysts point out that the adjustment in the AI hardware sector is not a sign of an overall industry decline, but rather a process of valuation repair. Although facing short-term pressure, the continued development of AI technology will provide strong support for the hardware sector in the long term. Especially with the growth in demand for inference chips, the AI hardware industry chain will usher in a structural opportunity.
Defensive Sector Rise: Dual Drive of Risk Aversion Sentiment and Defensive Value
In contrast to the AI hardware sector, the defensive sector performed strongly on September 18, with net capital inflows exceeding $2.5 billion in sectors such as utilities, healthcare, and consumer staples. The rise of the defensive sector is mainly driven by two factors:
Rising Risk Aversion Sentiment
With escalating geopolitical tensions globally and diverging US economic data, market risk aversion sentiment has clearly risen. Investors tend to allocate capital to defensive sectors with stable cash flows and low volatility. Data shows that net capital inflows to defensive sectors have been continuously increasing since September, especially in the utilities sector, which is favored by institutional investors due to its stable dividend policy and relatively lower valuation.
Prominence of Defensive Value
Against the backdrop of slowing economic growth, the defensive value of these sectors is prominent. The healthcare sector benefits from aging populations and growing medical demand, while the consumer staples sector benefits from inelastic consumer demand. These sectors have the characteristic of weathering economic cycles, providing relatively stable returns when economic uncertainty increases.
It is worth noting that the rise of the defensive sector does not mean a complete pessimistic shift in the market, but rather a rebalancing of risk preferences. Investors are maintaining a certain level of risk exposure while increasing defensive allocations to cope with potential market fluctuations.
New Energy Vehicles in China Attract Capital Against the Trend: Bright Delivery Data and Policy Support Align
In the backdrop of weak overall performance in large-cap stocks, the new energy vehicle sector has become the focus of capital. Chinese new energy vehicle stocks such as NIO, XPEV, and Li Auto have risen against the trend, with net capital inflow to the sector exceeding $800 million. This performance is mainly driven by three factors:Delivery Data Continues to Exceed Expectations
Several new energy vehicle companies announced their August delivery data in September, with NIO's vehicle deliveries increasing by 45%, XPEV by 38%, and Li Auto by 52%, all surpassing market expectations. Strong delivery data indicates that demand in the Chinese new energy vehicle market remains robust, especially the competitiveness in the high-end market continues to improve.Increased Policy Support
The Chinese government has recently increased its support for the new energy vehicle industry, including extending vehicle purchase subsidies and optimizing charging facility construction. These policy measures not only stimulate short-term demand but also provide policy guarantees for the long-term development of the new energy vehicle industry. Investors anticipate that, with policy support, the Chinese new energy vehicle industry will maintain a pattern of rapid growth.Technological Innovation and Product Upgrades
Chinese new energy vehicle companies continue to innovate in areas such as battery technology, autonomous driving, and intelligent cabins, continuously improving product competitiveness. Breakthroughs in areas such as 800V high-voltage fast charging, CTP battery technology, and urban NOA autonomous driving are further expanding the competitive advantage of Chinese new energy vehicles in the global market. The improvement in technological innovation capabilities provides a solid foundation for the long-term growth of the new energy vehicle sector. ## Asia-Pacific Market Opening Sentiment Outlook: Divergent Pattern May Continue Based on overnight stock fund flows and sector performance, the opening sentiment in the Asia-Pacific market shows the following characteristics:- Technology Sector May Diverge: AI hardware-related stocks may face some pressure, but application-layer technology stocks such as cloud computing and enterprise software are expected to perform relatively stably.
- Defensive Sectors Receive Attention: As risk aversion sentiment rises, defensive sectors in the Asia-Pacific market, such as utilities and healthcare, may attract capital.
- New Energy Vehicle Sector Expected to Remain Strong: The good performance of Chinese new energy vehicles may drive the bullish sentiment in the Asia-Pacific new energy vehicle sector.
- Semiconductor Sector Volatility Increases: Adjustments in the AI hardware sector may affect the overall performance of the semiconductor sector, but sub-sectors such as advanced packaging and specialized processes may be relatively resilient.
Short-Term Strategy: Seize Opportunities in Defensive Sectors
Against the backdrop of rising risk aversion sentiment in the market, appropriately increase the allocation ratio to defensive sectors. Focus on leading companies in sectors with stable cash flow, low valuations, and continuous dividend payout capabilities, such as utilities, healthcare, and consumer staples.Mid-Term Strategy: Focus on Structural Opportunities in the AI Industry Chain
Although the AI hardware sector faces short-term adjustment pressure, the long-term prospects for the AI industry remain bright. Investors should focus on structural opportunities in the AI industry chain, especially in sub-fields such as inference chips, AI applications, and data services. These areas have higher growth potential and stronger earnings certainty. ### Long-Term Strategy: Positioning in the New Energy Vehicle Industry Chain The new energy vehicle industry is in a high-speed growth stage, with significant long-term investment value. Investors should focus on new energy vehicle companies with technological advantages, brand influence, and economies of scale, as well as core component suppliers such as battery, motor, and power electronics control. Companies with leading advantages in technological innovation and product upgrading are expected to stand out in industry competition. ### Risk Management: Control Position Size, Diversify Investment Against the backdrop of increasing market volatility, investors should control overall position size and avoid overconcentration in a single sector or stock. By diversifying investments across different industries and styles of assets, it can effectively reduce portfolio risk and improve the stability of investment returns. ## Conclusion: Market Logic Behind the Rotation of Technology Sector Funds The rotation pattern of technology sector funds in US stocks on September 18 reflects the market's reassessment of the technology industry. The adjustment in the AI hardware sector is not a sign of overall industry weakness, but the result of valuation repair and earnings expectation adjustments; the rise of defensive sectors reflects a change in market risk preference; the strong performance of new energy vehicles demonstrates the powerful synergy of technological innovation and policy support. For investors, grasping the rhythm of technology sector fund rotation is crucial. Against the backdrop of rising short-term risk aversion, appropriately increase defensive allocations; focus on structural opportunities in the AI industry chain in the medium term; and position in leading companies and core suppliers in the new energy vehicle industry in the long term. By balancing defense and growth allocation, investors can seize structural opportunities amid market fluctuations to achieve stable investment returns. As the internal restructuring of the technology industry accelerates, investors should closely monitor changes in capital flows and adjust investment strategies promptly to seize investment opportunities in the technology sector rotation.
